WATER-CLOSET.

Specification of Letters Patent. Patented Sept, 20, 1921 Application filed me 4, 1920. Serial No. 386,506.

To all whom it may concern Be it known that we, lViNrrnLo E. HINs- DALE and WVILLIAM H. HALL, citizensof the United States,'residing at Trenton, in the county of Mercer and State of New Jersey, have invented certain new and useful Improvements in Tater-Closets, of which the following is a specification.

This invention relates to an improvement in water closets wherein the shape of the rim andthe water feed to same, whether in the regular shape bowl, or the vented bowl, 1S modified to procure a greater non-soiling condition and position of the rim and a more quiet feed of the flushing water to the rim than is possible in any of the existing models now made and procurable. 7

Two embodiments of the invention are disclosed in the accompanying drawings wherein,- 3

Figure 1 is a vertical longitudinalsection of a closet embodyingour invention,

Fig. 2 a horizontal sectional view, the plane of the section being'indicated by the line II II of Fig. 1;

Fig. 8 a transverse vertical section taken on the line IIIIII of Fig. l;

Fig. 5 a longitudinal sectional view of the rear portion of the closet showing the invention as applied to a closet having a local vent;

Fig. 6 a transverse vertical sectional view 1 taken on the lineVI-VI of-Fig. 5; and

Fig. 7 a horizontal sectional view taken on the line VII-,VII of Fig. 6.

Similar parts throughout the various views are indicated by the same reference numerals. 7

It will be understood that byreason of many years of use, the standardization of applied trimmings, and the necessity of a dimension standard, that the size of closets have become practically fixed, in that, it'is only necessary for the general dealer to know that a measurement of 16%,- inches from the center ofthe seat post holes will reach the front of thecloset, to. enable him to procure seats to fit. the same, orthat an extended lip closet will i go two. inches farther forward and that the seat post holes are always 5-3; inches center., Also that the width of he bowl is fixed at 14.- inches, and that the standard inside oval of the bowl rim is 10x 12 inches. This leavesthe dealer chamber.

free to select his stock of seats independent of the style of closet used. Therefore, it is also evident that to secure a rim that will give greater non-soil efliciency, it is neces sary to either enlarge the oval forward-as well as move the seat forward, thus destroying standards and creating greater expense in manufacture and carrying charge to the dealer and also a multiplication of hisstock, or, move the rim back without disturbing outside and fixed dimensions. \Vhen, howi ever, the rimis moved back, we find that interference occurs with the rear of the bowl, with the water feed to the rim and with the seat attachment if the bowl contour 'is not modified to overcome the interference. WVe have, notwithstanding this interference, moved the rear half of the inside oval of the rim to the rear and created a measure of 13 inches in the long diameter ofthe oval without moving the point of seat attachment or the outside oval of the bowl and rim.

The formation, contour and positioning of the oval with relation to the other parts is clearly indicated in the drawings, more particularly Figs. 1 and 2, from which it will be noted that while theou'tside dimension of the bowland rim is maintained standardfth e. inner 'dimension of the rim to the rim channel from the feed water chamber below the inlet and lying back of the bowl an'd rim and belowgthe closet top and the crown of the trapway' with ducts leading downward to the actuating jet l/Ve retain the I feed water chamber of practice, but'having found that the water entering such chamber came immediately in in any wiseaflect the measurement for the seat attachment and the holes through which mixed with the air and forced the air in its water mingled condition through the rim controlled orifices in an annoying noisy manner. This was particularly so in view of the fact that the control orifice led di rectly into the rim at which point the commingled air and water was forced to pass to the right and left to travel around the rim requiring a noticeable period of time for the air to become dispelled and a solid stream of water to be created. We have remodeled the structure so as to control the water entering the rim and take advantage of the entire section of the rear of the rim coincident with the feed water chamber placed at that point, the rear wall of which chamber is formed by a bridge or diaphragm through which the control opening passes.

Referring first to Figs. 1 to 4 inclusive 1 denotes the closet pedestal surmounted by the bowl 2. There is formed in the pedestal the usual siphon and trap passages 8 and 4, the latter leading to the outlet 5, all of which are of usual standard formation. The closet rim is denoted by 6 and while the outer dimensions thereof remain standard the inner contour is changed so that the rear portion or passage of the rim is narrowed, as at .7. This is effected by elongating the major axis of the inner oval of the rim. The rim is provided with the usual jet or stream orifices 8, some of which throughout the narrowed portion of therim are made smaller, as indicated at 9, so as to cause the water to flow around toward the wider forward portion of the rimfand thus insure an even feeding of the water outwardly from the orifices throughout the rim.

The closet is provided with the usual water inlet 10 which opens into a chamber 11 above the'crown12. of the trap,andsupply assages 13 and 14, which extend downwardly along" the sides of the siphon, the same terminating in the, usual -water supply chamber 15 into which opens the jet orifice 16. The diaphragm or bridge-like member 17 is placed across the forward end of the chamber 11, said member or bridge being spaced rearward from the rim proper forming a secondary chamber 18 which at its forward portion opens directly into the rim, and a regulating opening 19 of determined size is formed in the bridgeor diaphragm 17 and consequently controls and determinesthe amount of water which may pass into the auxiliary chamber 18 and thence into the hollow rim. The openings for attachment-of the seat securing means are indicated by 20 and as before stated'said openings bear the same relation to the outside dimensions of, the bowl as in the usual standard closet so that the length of the inner oval and the inner dimensions of the rim do not many wise affect the utilization of seats of standard size.

above the closet.

Opening up the rear section of the rim by the provision of the auxiliary chamber 18 may be said to add that section of the rim to the chamber, thus allowing ample area in the rim channel on either side of the forward end of the chamber 18 for the passage of water into the rim channel. It has the added advantage that as the water from the inlet 10 enters the water feed chamber 11 it falls first to the normal water level of the bowl and chamber and as it rises forcing the air ahead of it, to and through the control orificeror opening 19,

where, entering the chamber 18 it finds largely increased area and its force is therefore destroyed before it gathers again to enter the rim channel. The openings in the rim channel at the point of juncture or mergence of said channel with the chamber .1

'18 are each approximately equal in area to that of the control orifice or opening 19, the result being that the water flows easily into the rim channel and any air that may be commingled with the water at that time finds easy and quiet egress through the'rim apertures. By this method of construction we have obtained a quiet flushing closet and with a rim of continuous conventional oval form have obtained the maximum removal accepted space details now more or less standard with all makers.

A second embodiment of the invention. is shown in Figs- 5, 6 and 7, said closet being of the vented type- The closet embodies the same ideaof non-soil rim construction and there is present a vent passage orduct 21' originating in the bowl under the rear segment of the rim, thence passing upwardly above the'trapwayand under the extended closet top, rising through the same at a point to the rear of the regular seat attachment and terminating at its rear entirely No claim is made herein to such vent passageor duct, as that is set forth and claimed in an application filed by WinfieldE-Hinsdale, on or about the 17th day of July, 1917, Serial No. 181,069.. By reason'of this vent passage or duct a slight modification in the water supply to the rim is necessary. The water supply in this instance is designated by 22 and ducts or channels 23 and 24 pass downwardly to each side'of the vent'fduct '21 to the jet ao-' tuating chamber 25.1 .A chamber 26 corresponding to the chamber 18 of the form 'first described, is formed in. the body of the closet in rear of the restricted portion of the flushing rim, and is in directfcommunication therewith. The rear wall of said chamber is formed by the upper wall of the vent duct 21, and bridge pieces or diahragms 27 and '28 are interposed between said wall and the rear portion of the chamber 26, control openings 29 being formed in each of said diaphragms and affording communication between said chamber 26 and the passages or ducts 23 and 24. These two openings or orifices 29 are of determined size and perform the sameofiice and function as the orifice 19- in the construction first described, but being made of a lesser area each, to equal in their sum the area of the orifice 19. In this closet, as in the non-vented type, it will be seen that the falling water in a practically solid stream from the inlet reaches the normal water level before it can mix with any of the interposed air. Its weight immediately starts the jet in action and the escape of water through the jet is not great enough to take the volume delivered and the excess of supply raises the water level to the rim controlled orific or orifices, which by reason of its placement, as above set forth, allows easy escape for air and a consequent quiet entry of water into the flushing rim, the volume of which flow, as explained, being controlled by the predetermined size of the orifice 19 or the two orifices 29 in the construction last described.

It will be readily appreciated by those skilled in the art that the novel construction as tori'm shape and rim water feedmaybe applied to closetsof types other than the two herein specifically set forth, as the construction is readily adaptable to wash-down and ejector typebowls as well.
